We Boost It — and Check Why It Died

What Is a Mobile Jump Start?
A mobile jump start is a come-to-you service that safely boosts a flat or dead vehicle battery using professional jump packs, so your engine starts and you can drive again. Recovery Giant reaches most UK drivers in under 45 minutes, checks why the battery went flat, and if it can't be revived, recovers it to a garage or battery shop.
Signs It's Your Battery
Not sure what's wrong? These are the tell-tale signs of a flat or dying battery — the most common reason a car won't start.
It clicks, or nothing
Turn the key and you hear a click, or silence.
Dash lights dim or flicker
The lights are weak or flicker when you try to start.
No lights, no dash
Completely dead — no interior lights, no dashboard.
Slow to start lately
The engine's been cranking slowly or hesitating.
Battery a few years old
Most car batteries last around three to five years.
Dead after a cold night
Cold weather drains batteries, especially older ones.
Lights left on overnight
Headlights, an interior light or a door left ajar.
Electrics playing up
Odd electrical gremlins can be an early warning.
Sounds like your battery? We'll know for sure
These are the classic signs — but a jump start also shows whether the battery will hold its charge. Our on-site check finds out if it's the battery, the alternator, or something else, so you're not guessing.
Is It the Battery — or Something Else?
A jump start gets most cars going — but not always. Here's how to tell what's really wrong, and how our on-site check confirms it.
Flat or failed battery
Alternator
Starter motor
Is it my battery or my alternator?
If a jump start gets you going and the car keeps running, it's usually the battery. If it jump-starts but dies again shortly after, the alternator may not be charging. Our on-site test confirms which — before anything is replaced.
Yes, We Jump-Start EVs & Hybrids
Electric and hybrid drivers get turned away by a lot of jump-start services. Not here — we're equipped and trained for the 12V batteries modern cars still rely on.
Wait — you can jump-start an EV?
Yes. Electric and hybrid cars still have an ordinary 12V battery that powers the lights, locks and computers and "wakes" the car so it will switch on. If that 12V battery goes flat — in the cold, or after sitting unused — the car won't start, even with a full traction battery. We boost the 12V battery with EV-safe equipment and the correct procedure, and never touch the high-voltage pack.
More on EV & hybrid recoveryWhy It's Safer to Let Us Do It
A DIY jump start can go wrong on modern cars. Here's why it's safer to let a pro do it — and how to stay safe while you wait.
The risks of doing it yourself
How we do it safely
- Professional jump packs — no second car, and no crossed leads.
- We check the battery and terminals before we connect anything.
- The correct procedure for your vehicle, including EV and hybrid 12V systems.
- If the battery has failed, we tell you and recover it — no guesswork.
What should I do while I wait?
Put your hazards on, and if you're on a busy road get somewhere safe off the carriageway. Don't keep trying the ignition — repeated cranking drains the battery further. Keep your phone on for your technician's ETA call.
Can I use a portable jump pack myself?
You can, if you're confident and follow the instructions exactly — but on modern and electric cars a wrong connection can be costly. If in doubt, leave it to us — we do it safely every day.

Jump Start Questions
The things drivers ask us most — answered plainly. Still stuck? Just call.
What is a mobile jump start?
A mobile jump start is a come-to-you service that safely boosts a flat or dead battery using professional jump packs, so your engine starts and you can drive again. We also check why it went flat, and if it can't be revived, recover it.
Do I need a membership?
No. There's nothing to join and nothing to renew. You pay per job, only when you need us, with the price confirmed upfront.
Can you jump-start an electric or hybrid car?
Yes. EVs and hybrids have an ordinary 12V battery that can go flat like any other. We boost it with EV-safe equipment and the correct procedure — we never touch the high-voltage traction battery.
Is it the battery or something else?
Not always the battery. If it jump-starts but dies again soon after, it may be the alternator; a single click with good lights can be the starter. Our on-site check confirms which before anything is replaced.
What if the jump doesn't hold?
If the battery has failed and won't hold a charge, we'll tell you on the spot and recover it to a garage or battery shop — same crew, no second call.
Can you replace my battery?
We'll always tell you if the battery has failed. If it needs replacing, we'll advise you and can recover the car to a battery shop or garage. Ask when you call and we'll let you know what we can do on the day.
How fast can you reach me?
Most UK drivers are reached in under 45 minutes. We give you an ETA the moment you call and keep you updated until your technician arrives.
Are you available 24/7?
Yes — 24 hours a day, 365 days a year, including weekends and bank holidays. A real dispatcher answers every call.
